You can use the saphost agent, or directly the isql command line

Using the SAP host Agent:

# /usr/sap/hostctrl/exe/saphostctrl -function StopDatabase -dbtype syb -dbname DEV -service


Using the isql Command line:

# isql -Usa -Ppassword -Sserver_name -X

1> shutdown

2> go

 Issuing the shutdown command prints a message such as this to the sterr file:

Server SHUTDOWN by request.The SQL Server is terminating this process.
